TYPE-WRITING MACHINE.

Original application led February 15,

To all ywhom t may concern Be it known that I, EMMIT G. LATTA, a citizenof the Unit-ed States, residing at t yracuse, in the county of Onondagaand State of New York, have invented a new and useful Improvement inType-Writing Machines, of which the following is a specification.

This invention relates to improvements in front strike or visiblewriting typewriting machines in which the type-bars are mounted on asupporting segment which is adapted to be shifted for placing one oranother of the sets of type on the type-bars in printing relation to theplaten.

This 'applicationis a division of my copending application Serial No.608,657, tiled February 15, 1911. v

One object of the invention is to provide a typewriting machine of theMoyer make with a shiftable type-bar segment and adapt the ri-bbonvibrating mechanism and other features of the machine for coperationwith such a shiftable segment, as hereinafter described and set forth inthe claims.

Other objects'of the invention are to provide a typewri'ting machinehaving a shift able type-bar segment with eflicient and practicalmechanism for operating the ribbon vibrating device as well 'as thecarriage escapement by the'direct action of the typebars; also toarrange and connect the parts of the machine in such a way that they canbeassembled and dismounted with ease and rapidity; also to connect'theribbon vibrator lever directly to the universal bar without the useofintermediate or separate` loose connections, and to do this in a waythat permits of different motions of the vibrator for moving either oneof a plurality of different portions or fields of the ribbon to and fromposition for printing, and permits the ,vibrator to be thrown out ofaction; and also to improve visible writing typewriting machines in theother respects hereinafter described and set forth in the claims.

mentary similar sectional elevation showing the'position of the partswhen the segment is shifted. Fig. 3 is a longitudinal sectionalelevation, on a reduced scale, of the top plate of the machine. Fig. 4is an enlarged sectional elevation of the operating means for the ribbonvibrator. Fig. 5 is a plan view, partly in section, of the machine, thecarriage being removed and the carriage guide being partly broken awayto disclose the underlying parts. Fig. 6 is a rear elevation thereofpartly broken away and partly in section, in line 6 6, Fig. 1. Figs. 7and 8 are respectively a fragmentary longitudinal sectional elevationand a rear elevation, partly in section, of a modified construction.

`The construction illustrated in Figs. 1-6 will be first described.

A represents the main frame of the machine; B the top plate thereof; Cthe platen carriage which supports the platen c; D the carriageescapement; E one of the type-ba'rs which are pivoted in an arc belowthe carriage so that the type-bars can swing upwardly and rearwardly tomake the impressions at the front side of the platen; F the key leversand f one of the auxiliary levers operated thereby for actuating thetype-bars. These parts, except as hereinafter explained, areconstructed, arranged and operate as in the Moyer typewriter and areillustrated to show their relation and coaction with the other parts ofthe machine.

The top plate B preferably consists of a single casting of substantiallyuniform thickness throughout which is removably secured on the mainframe A, for instance, by screws b, Fig. 5, at the four corners of theThe front and rear portions of the top plate are in different horizontalplanes and the connecting middle part is curved as shown best in Fig. 3.The middle part has two raised side portions b b', Figs. 3 and 5,forming forwardly inclined flat seats for a carriage track or guidemember or casting B. The central part of the top plate is removed orprovided with an opening b2 having large ,front and rear portions and anarrow connecting portion to permit the type-bars to swing to the platenand to admit the universal bar, ribbon vibrator and other parts whenassembling them in the machine. The horizontal front portion of the topplate is preferably provided at opposite sides with depressions frhaving inclined bottoms to enable the ribbon spools, one of which isshown at 6*, Fig. l, to be arranged in an inclined position with theirfront lower edges below the surface of the front part of the top plateso as to deliver the ribbon in line. with the ribbon vibrator.

The carriage track member or casting B supports the guide or track onwhich the carriage travels transversely of the machine. The carriagetrack or guide Ff shown is of ball bearing type used in the Moyermachine., but a track or guide of an) other suitable sort could be used.The. track casting B is rigidly secured on the inclined seats L of thetop plate, for instance, by four screws 71", two of which are shown inFig. By the use of a separable track member or casting secured on thetop plate the machine can be readily supplied with track castings of different lengths suitable for different length carriages, and the castingwith the parts carried thereby can be readily secured in place andremoved from the machine.

The carriage escapement D is mounted on a suitable bearing )art (l onthe rear `central portion of the traclc castin B', the shaft d: of theescapement wheel belng, as usual, proyided at its front end with a gearpinion Z2 which meshes with a rack bar d3 on the carriage.

G represents the segment or support for the type-bars. The.segment'preferably consists of a curved or segmental casting having aslotted iange projecting forwardly from its upper edge in which hangersg for the type-bars are secured by a clamping plate g and screws g2missin; through the plate and between the linger mto the segment, as inthe Moyer machine. The segment is movably mounted so that it can be,shifted vertically on a central arm h and two side arms 7b k', the frontends of which are pivoted in slotted lugs h2 on the rear side of thesegment. The side arms h k yare rigidly secured at their rear ends to arock shaft H which is suitably journaled at its ends on the oppositesides of the main frame, and the central arm h is forked and has therear ends of its two branches pivoted in lu'fs h3 projecting upwardlyfrom a bar itt which is rigidly secured to the rear portion of the mainframe and to which the rear ends of the key levers are pivoted. Thesegmentsupporting arms are parallel and thus hold the segment upright inits normal and shifted positions.

I represents a cam or cam lever for shift ing the segment. This shiftingcam is fixed centrally on a horizontal rock shaft a' and is providedwith a cam slot in which Works a roller e" journaled ou a bracket 2which is secured in any suitable way to and projects forwardly from themiddle of the segment. The end portions of the cam slot are preferablysubstantially concentric with the axis of the cani so that the segmentwill be locked from movement when the roller enters either of these endportions of the slot. The rock shaft i is journaled at its ends on thesides of the main frame and. has rigid forwardly projecting arms i atits opposite ends which rest on the upper rocker-shaped edges of shifthey-levers i fulcrmned at i5 between their ends. (.)ne of the shiftkeylcrers is shown in Fig. l. By depressing the front end oteither ofthe shift keydevers the rock shaft and cam il, are 'rocked with an:uceleratiuUr motion and shift the segment. together with the type-barsand other parts supported thereby, from the position shown in Fig. l tothat shown in Fig. 2. suitable springr i", lig (i, on one end of therock shaft 2'y arts to start the rock shaft und cam from the shiftedposition as soon as the shift keyle\er is released. llvhcn the rollerpasses out of the concentric end portion of the cam slot the weight ofthe segment and the parts thereon will force the cam back to its normalposition. A spring (not shown) is usually employed to partially supportthe weight of the shifting parts and reduce the exertion necessary toeffect the shift. The location of the shift cam centrally under theshifting parts or substantially at the center of gravity thereof makesthe shift action quick and easy.

The segment is preferably mounted and shifted as above described, but itcould he differently mounted and shifted by other means.

As indicated by the shade lines in Figs. l and 2, both the centralkey-lever I" and the auxiliary lever f are slightly offset sidewisewhere they pass the shift cam to make room for the movement of the cambetween these closely arranged parts.

The universal bar, as heretofore in the Moyer typewriter. consists of arock shaft which is operated by one or more actuators which are struckand moved by the typediars as they approach the platen. K l( representthe universal bar actuators and li the uni versal bar.

'The two actuators K l( are shown in the construction illustrated inFigs. l-l of the drawings. They consist of two curved bars arranged overthe pivoted ends of the type bars so that each actuator is adapted to bestruck and actuated by any one of the typebars on the adjacent half ofthe segment just before the type-bar reaches the platen. Each actuatoris supported by two bars 7c 7.5 which are rigidly secured to and extendrearwardly from the actuator and are pivoted to the upper ends of armsk2 [c2 extending upwardly and inwardly from a rock shaft 7c3 journaledon the segment, for 1nstance between two pivot lugs le* on the rear sideof the segment. The inner supporting bars k k' of the two actuatorsextend beyond the arms k2 k2 of the rock shafts and are pivotallyconnected to the upper ends of links k les which are suitably pivoted attheir lower ends to the rear ends of brackets les 7c rigidly secured toand projecting rearwardly from the segment. The supporting bars k It"preferablyr consist of sheet metal stampings and have lateralprojections at their front ends which are bent to fit the actuators, towhich they are riveted, and the inner bars la it" have cross pieces tfat the rear ends which are slightly twisted so as to stand vertically infront of the lower ends of arms Z whlch are fixed to and depend from theuniversal bar L. The rock shafts k3 k3 cause a corresponding motion ofboth ends of the actuators when struck by the typebars regardless of thepoint at which the actuators are struck, thus insuring a uniform actionof the universal bar and the parts operated thereby, and the connectionof the links lc5 h5 to the extensions of the bars lo L" acts to retainthe actuators K K in their proper relation to the type-bars and causethem to move in a substantially horizontal direction. ln the normalposition of the segment, shown in Fig. l, the upper parts of the rearends of the bars c L" rest against the lower ends of the arms Z l of theuniversal bar, and when the segment is shifted the lower parts of saidrear ends rest .against the arms l Z, as shown in Fig. 2. Therefore theaction of the universal bar is the same in both positions of thesegment.

les n represent springs for returning the actuators to the normalposition after actuation. Coil springs are shown for this puri poseconnected at their rear ends to the actuator bars k -k and at theirfront ends to a bracket la" secured to the segment.

The universal bar L is preferably journaled on end pivots l l which arefixed by arms l2 to a supporting rod l which is arranged to slideendwise in bearings l4 on the underside of the trackfcasting B. Thesupporting bar is detachably connected, for instance, by a` pin Z5, Fig.6, with a shifting lever or device (not shown) whereby the universal barcan be readily adjusted endwise to either of four different positions.The pivots l' l' for the universal bar preferably extend through guideholes in the bearings l* on the track casting B. l represents a springfor returning the universal bar to the normal position. The spring shownconnects one of the universal bar arms l to a bracket l* fixed tc thesupporting rod Z3, so that the spring is not affected by the adjustmentof the universal bar. The universal bar operates the carriageescapeinent D preferably by an arm 8 which projects rearwardly from theuniversal bar and is connected by a link /9 to the pawl lever of thecarriage escapcmcnt.

M represents the ribbon 1vibrator or guide for vibrating the ink ribbonm to and from the printing position between the type-bars and theprinting point of the platen. The vibrator, 4which may be of theconstruction shown or of any other suitable construction. is preferablyarranged to reciprocate vertically on a stationary upright guide m andis connected at its lower end to a vibrating or operating lever m2. Asshown, the vibrator guide m is rigidly secured by screws. or otherwise,to the front end of a forwardly projecting extension m3 of the trackeast.- ing B', and the vibrator M is confined between the rear side ofthe guide m and a line gage and center scale m* which is secured to therear side of the vibrator guide m. The lower portion of the vibratorextends downwardly through a slot in the eX- tension m3 of the trackcasting B and has a rearwardly bent lower end which enters and isremovable from a slot in the front end of the vibrator lever mi. Thevibrator and its guide have registering holes through -which the scaleon the scale bar m5 of the carriage can be seen, and the vibrator isprovided with an index or pointer m coperating with said scale toindicate the position of the printing point. The upper ends of thevibrator M. vibrator guide m and the line gage m* are slotted centrally,as shown, to allow the heads of the type-bars to strike the ribbon inmaking the impressions.

The vibrator lever m2 is suitably fulcrumed between its ends at m7-onthe lindersideof the track casting B and is provided N represents an armrigidly secured to the universal bar and provided at its end with teethwhich are adapted to mesh with the toothed segment ms, and n, is an armlocated at Ione side of the arm N and provided with offset teeth at itsend adapted to enter the opening in the lever and mesh with the toothedsegment m9. Preferably the arms N and fn, are separated by a spacingwasher n', these three parts being riveted together and rigidl)7 securedto the universal bar by soldering or otherwise, and the arm N is made inone piece with the escapement actuating arm Z8.

ln the position of the parts shown in Figs. l and 5, the teeth of thearm N mesh with the teeth m3 at the rear end of the vibrator lever andwhen` the machine is operated the upper portion of the ribbon, or theupper lield thereof, in the case of a rib- 'sob bon having differentfields, will be vibrated to and from the printing position. By movingthe universal bar to the right, as viewed in Fig. 6, the teeth of thearm N are moved out of mesh with the teeth ms of the vibrator lever andthe teeth of the other arm n are placed in mesh with the other teeth mof the vibrator lever and then the lower portion or field of the ribbonwill be vibrated to and from the printing position when the machine isoperated. lf the universal bar is moved to the left, to a thirdposition, the vibrator lever is freed from both of the arms N and n andthe ribbon vibrator will then remain inactive when the machine isoperated, thus permitting the cutting of stencils.

The lower ends of the arms Z 7 of the uni-1 versal bar are provided withcross pieces or lateral eXtensions of sufficient width to be engaged bythe actuator bars 7: le in either of the three positions of theuniversal bar just mentioned. If, however, the universal bar is movedstill farther to the left, the lower ends of the arms Z Z are moved outof line with the actuator bars 7c le', and then either of the actuatorsK can be moved rearwardly from above the type-bar hangers g so that thehangers can be detached from the segment by loosening their securingscrews and disconnecting the type-bars -from their actuating linkswithout removing the clamping plate g for the hangers. The lower end ofthe actuating link Zn for the escapement swings laterally when theuniversal bar is shifted., but the movement thereof is not great enoughto interfere with the perfect action of the escapement in the threeoperating positions of the universal By locating the escapementoperating arm ZB of the universal bar over the rear portion of the topplate,l as shown in Fig. 1, providing the openings in the top plate, anddetachably connecting the universal bar to its shifting device, thetrack casting B with the complete carriage, universal bar, escapementand ribbon vibratingr mechanism can be detached from the top plate, bysimply removing the securing screws for the casting, detaching theribbon from the vibrator, and disconnecting the draw-band fn* thatconnects the carriage to its spring driving drum. This is a greatconvenience in assembling, cleaning and repairing the machine, and inchanging it for carriages of dierent lengths. It will be observed thatthe universal bar is not connected tothe actuators on the segment andconsequently there are no parts requiring to be disconnected to permitthe removal of the top plate or the track casting with the partssupported by the same.

The ribbon feeding and reversing mechanism form no part of thisinvention and are therefore `not shown or described, but this mechanismis mounted as heretofore, on the top plate B, and as the ribbon spoolsand the vibrating mechanism are also mounted on the top plate, as shown,it will be evident that the top plate with the complete ribbon operatingmechanism, together with the other parts mounted on the top plate, canbe removed from the machine by simply detaching the top plate andwithout disconnecting "any other parts.

O represents a center guide for properly guiding the type-bars to theprinting point on the platen. The center guide is secured by screws, orotherwise, to an upwardly pro.- jecting horn or extension o on themiddle portion of the segment. This horn curves rearwardly just abovethe segment or has a recessed front side otherwise formed to afford roomfor the actuators K to be moved to the rear far enough to permit thedetachment of the type-bar hangers from the segy ment. as beforeexplained. The center guide 0 extends upwardly and forwardly from thesegment to a point in front of the lower end of the vibrator guide m',then vertically in front of the latter, and its reduced upper end oextends rearwardly into the slotted upper e'nd of the vibrator guide.This upper end o of the center guide is slotted to receive the guidingheels or parts 02 at the outer ends of the type bars. The center guide,which shifts with the segment G, has an elongated opening o3 to enablethe scale bar Vm5 to be seen through the openings of the ribbon vibratorM and its guide m', in either' position of the center guide, and thecenter guide also has a larger opening 0* below the opening o3l thatadmits the lower end of the vibrator guide, the vibrator, and the frontend of the vibrator lever m2 when the center guide is in the raised orshifted position. lhile the center guide O shifts with and thus alwaysretains the same relation to the type-bars, the vibrator guide m' isstationary and remains in the same relation to the vibrator M.

P represents the back stop, or rest, for supporting the outer ends ofthe type-bars in the normal position thereof. This back stop is alsosupported from the segment so as to shift therewith, for instance, byposts p which are rigidly secured to the ends of the segment in anyconvenient way and project forwardly therefrom Figs. 7 and 8 show amodified construction of the segment, anduniversal bar mecha nism whichis less expensive than that before described. In this construction, Grepresents the segment. The type-bars E Vare pivoted on the segment by acurved pivot wire g, thereby dispensing with the separate hangers andbearings used in the first construction. A single curved universal baractuator K is used which is long enough to be struck by all of thetype-bars, it is supv ported by two rock shafts 'y' journaled one inrear of the other in brackets f/`l projecting reawardly from the segment(i and having upright arms o and (it, respectwly, which are pivoted tosupporting bars on projecting rearwardly from the actuator K. 'l` heuniversal bar L has a single, pendent arm q pivoted .to the rear end ofa link q" which it its front end has a pin and slot connection q2* witha bracket fl" on the actuator. The pivot between the link and thcactuator normally occupies a position below the level of the pivotbetween the link and the arm o". and when the segment is shifted theformer pivot occupies a position a` corresponding distance above thatlevel;y so that the action o f the escapement and ofthe ribbon `vibrator.will be the same in both thc normal and shifted positions of thesegment. The pin and slot connection o* allows the actuator to return tono rmal position in advance of the return of the universal bar, and the.connections atthe ends of the link are loose enough to permit theuniversal bar to be moved to change the throw. of the ribbon vibrator asbefore described, without alter-ting the actionof the'universal bar.This segment is mounted and operated in the saine way as that firstdescribed and. as in the first coustruction', the universal baractuator. the center guide O for the type-bars, and the back stop P forthe type-bars are supported by and shift the segment. The segment andthe parts supported thereby with but slight changes in one or two of theparts. are interchangeable with the correspoiuling parts in 4theconstruction first ijlescribed. This modified construction is lessdesirable than .that first described, but itlinyolyes a greatly reducednumber of parts and therefore desirable for use in cheaper machines,y asit Venables* the manufacturer to produce machines of twoy grades withbut little more ex- 'pense than for one.

lVhile it is one of the objects ol this in- `vention to attuate theoperating mechanism for the ribbon vibrator and carriage escapement bymeans supported by a shiftable segment carrying type-bars provided witha plurality of sets of type, the invention is not necessarily restrictedin applicationto a machine having such a shiftable segment as it isdesirable for some purposes to support the ribbon vibrator andescapement actuating means` on a segment which does not shift whetherprovided with type-bars having a single set of type. or more than oneset of type and used with a shifting platen.
